Types Of Errors; Error Coding - Promax MO-170 Manual De Instrucciones

4.11.1 Types of errors

The control program of the MO-170 can detect and show up to 4 types of errors.
Some of them correspond to instrument malfunction and must be directly reported to a
PROMAX's Customers Service Centre (CSC). Others state incorrect options about
modulator input signals.
1. NAK: An internal device connected to control I
messages from the microcontroller. It requires service of CSC.
2. UNKN: Unknown error. Due to a problem different to the one previously
described, the I
CSC.
3. BUSY: The I
operation. It requires service of CSC.
4. MOD FAIL: It covers all errors corresponding to the MPEG-2 transport stream
inputs not being correctly synchronized and/or not having the right bit rate.

4.11.2 Error Coding

NAK, BUSY and UNKN are for internal use of Promax. If any of these errors
occurs repeatedly, the equipment ought to be taken to a PROMAX's customer service
centre for repair.
MOD FAIL: The display format for this type of errors is as follows:
ERR02 MOD FAIL STATUS: XXYY (CCC...C)
When this type of errors occur, the MO-170 presents an error message on the LCD
display starting with the word STATUS and followed by an explanation of the type of
error (e.g. HP TS SYNC LOST, LP TS BUFFER FULL or INVALID TS RATE). Needless
to say, in this scenario the ERROR LED flashes red for 5 seconds, and then stays lit
until the error count is cleared within the CONFIGURATION menu.
The numerical fields have the following meaning:
XX: Hexadecimal value composed by several information bits, with meaning
according to the modulator configuration. Eight bits compose the data structure. Each
bit marks an error status when its value is "1", except when the opposite is indicated:
